| Abstract: | The geothermal resources discovered in India consist of warm/hot water systems. Medium-temperature waters and reversal of temperature at depth were observed in Puga, Manikaran and the West Coast geothermal areas after exploratory drilling. Such resources can be utilized only for non-electrical applications after detailed technical—economic feasibility studies. The presence of medium-temperature (90–140°C) springs in the cold, remote and steep Himalayan terrains and of lower temperature springs (100°C) in the hot and variable climate of the Peninsular and Coastal regions further restrict full utilization of these resources, with the exception of Cambay, West Coast and Tatapani—Jhor areas. After careful study a list of direct utilizations is proposed for future consideration and the development of the main geothermal resources in India. |
